Figure 1

The effects of GBH and CGA treatments on AST (A), ALT (B), ALP (C), urea (D), and creatinine (E) levels in the serum of Wistar rats. Values are expressed as mean ± SD of seven rats per group. Different superscripts (a–c) above the bar indicate significant difference between groups (p<0.05)

H&E-stained slides showing the protective effects of CGA against GBH-induced damage in the brain (A), heart (B), liver (C), and kidney (D) of Wistar rats(20× magnification; scale bar 200 µm). 1 – control; 2 – CGA50; 3 – GBH; 4 – CGA12.5+GBH; 5 – CGA25+GBH; 6 – CGA50+GBH. Slides A3–A6: arrows indicate neuronal degeneration and focal gliosis; arrowheads indicate hyperaemia in the vessels and curved arrows indicate neuronal vacuolation in the brain. Slides B3–B6: arrows indicate myocardial hyaline degeneration; arrowheads indicate focal haemorrhage in the heart. Slides C3–C6: arrows indicate mononuclear cells infiltration in periportal areas; arrowheads indicate sinusoidal dilatation and curved arrows indicate binucleated hepatocytes in periportal areas in the liver. Slides D3–D6: arrows indicate degenerative and necrobiotic changes in tubular epithelial cells; arrowheads indicate hyaline cylinder formations within the lumens of tubules in kidney tissue
